Title: Phase difference measuring system
IPC: G01R25/00
Filed: 1968-01-11
Abstract: 1,146,429. Radio navigation. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Jan., 1968 [13 Jan., 1967], No. 1736/68. Heading H4D. The Specification describes a phase difference measuring system in general, with particular reference to its use in a radio direction-finding arrangement, wherein radiations from a satellite are received at two spaced ground stations 24, 25, with phases, the difference between as determined by said system, represents the direction of the satellite. Ground station 24, receiving first signal F o  |#α 1  comprises a first phase locked loop 4/12 which produces an output signal 13 |#α 1 +# 1  from a voltage controlled oscillator 8. Ground station 25 receiving second signal F 0  | #α 2  also comprises a phase locked loop 14/18, 20/23 into which, by means of mixer 19, the output signal of the first phase locked loop is introduced, whereby the output of the voltage controlled oscillator 18 is a signal having a phase |#α 2  - α 1 + #2  - # 1  containing the desired phase difference term |#α 2  - α 1 . In station 24 (station 25 being substantially similar), the signal F 0 |#α 1  at the output of amplifier 3, is converted to an IF signal 30|## 1  in mixer 4 by means of a signal (F o +30)|#α 1 +# 1  from mixer 9. The IF signal is then phase compared at 6 with a reference signal 30 90‹ and a resultant signal representative of # 1  is passed via low-pass filter 7 to the control terminal of voltage controlled oscillator 8. The output 13|#α 1 +# 1  of the oscillator 8 is converted to the signal (F 0 +30) |#α 1 +# 1  in mixer 9 by means of signal (F 0 +17)|#0‹. Fig. 4 shows an embodiment wherein phase shifts produced by amplifier 3 are allowed for and counteracted. A mathematical explanation of the invention is given.

Patent GB-163748-A (GB)
Title: Improvements in governing mechanism for impulse turbines
IPC: F01D17/00
Filed: 1920-01-22
Abstract: 163,748. Muir, A. Jan. 22, 1920. Fluid relays.-The throttle valves of impulse turbines are operated by means of a pressure fluid servomotor system, the pressure in which is controlled by a release device actuated by the governor. In mixed pressure turbines an automatic valve cuts out the low pressure steam if the pressure is too low. The governor 8 is driven by an auxiliary shaft through worm gearing and comprises a worm wheel formed in two parts, a centre portion which carries the governor weights, and a removable rim portion of antifriction metal. A piston 7 is connected to the governor and rotates in a bushing 6 provided with a port 40 of triangular shape. The bushing serves as a release valve to an oil pressure system operating a servomotor 10 which is connected to a throttle valve 3 by means of self-aligning couplings. The sensitivity of the control can be adjusted by a valve 4 in the oil pressure system. The throttle valve may be opened by a lever at starting when there is not sufficient oil pressure. By raising the bushing 6 by means of a hand wheel 23 or by a distant control the speed of the turbine can be varied. A non-rotating rod connected to the governor through the piston 7 indicates the speed on a dial. Fig. 5 shows the arrangement for mixed pressure turbines. The low pressure throttle valve 44 is set by the hand adjustment 49 to open before the high pressure throttle valve 45. A device for cutting out the low pressure steam may be inserted at 50. This is shown in Figs. 6 and 7 and operates when the pressure is insufficient. The low pressure steam acts on a non- corrodible piston 53 against the pressure of an adjustable spring 54 and forces a plunger 59 into the annular oil passage of a semi-rotary leaf type pilot valve 52, the oil in the space 58 draining away through a hole in the plunger so that the unbalanced oil pressure at 61 opens the valve and permits the pressure oil to flow to the low pressure servo-motor. Any steam passing the piston 53 is drained off.

Title: Process for the production of cracking catalysts, and their use in catalytic cracking
IPC: B01J21/14
Filed: 1958-01-22
Abstract: A cracking catalyst is prepared by adding to an aqueous sodium silicate solution, while maintaining the pH at at least 10, an aqueous solution of one or more salts of magnesium and/or calcium in an amount from 1/50 to 1/5 mols. of the salt per mol. of SiO2 in the silicate solution, adding to the mixture a solution of an aluminium salt and adding aqueous ammonia solution during at least the final stages of the aluminium salt addition to maintain the pH between 9.0 and 10.5, filtering the resultant hydrogel from the liquid and washing and drying it.  The SiO2 concentration prior to the addition of the aluminium salt is between 3 and 9%.  The solution of the magnesium and/or calcium salts is 0.05 to 0.5 molar.  Before, during or after the addition of the magnesium and/or calcium salts, acid is added to obtain a pH of the mixture between 10 and 10.5.  More acid may then be added to lower the pH to between 9.0 and 10.5, preferably 9.5, and this is maintained during the addition of the aluminium salt and the ammonia.  The finished catalyst may contain between 12 and 30% by weight of alumina, and between 1 and 9% by weight of magnesium and/or calcium calculated as MgO and CaO.  An alkali metal ammonium salt may be added to the sodium silicate before the addition of the magnesium and/or calcium salts.  Examples are given.

Title: Improvements in or relating to semi-conductor arrangements and methods of producing such arrangements
IPC: H01L21/00
Filed: 1960-01-21
Abstract: 896,730. Transistors. SIEDMENS & HALSKE A.G. Jan. 21, 1960 [Jan. 27, 1959], No. 2299/60. Class 37. A unipolar transistor comprises a body of one conductivity type with a surface layer of opposite conductivity type and of higher resistivity, formed by impurity diffusion, spaced portions of which are provided with ohmic contacts. In the embodiments a further layer of the same conductivity type as the body is provided on the first layer between the ohmic contacts. In one embodiment the first layer, which is a P-type layer 9 (Fig. 5), on a circular N-type disc 4 is provided with a central ohmic electrode 1, annular ohmic electrode 2, and an annular N-type layer beneath electrode 3. In another arrangement a P-type layer 9 surrounding an N-type cylinder (Fig. 4a) is provided with an annular N-type layer associated with electrode 3, and annular ohmic electrodes 2. Alternatively (Fig. 4b) the N- type layer extends the full length of the cylinder, in which case washer shaped ohmic contacts are provided at the ends of the cylinder. In this arrangement short-circuiting of these contacts through the N-layer is avoided by removing the layer from annular zones adjacent the contacts. Planar layers are used in the device shown in Fig. 2 in which the ohmic contacts to P-type layer 9 are aluminium wires 1, 2, alloyed through layer 3. The layer is divided by cuts 16 to avoid short-circuiting. In another planar arrangement (Fig. 3), the further layer 3 and the ohmic contacts disposed as shown are formed by alloying gold antimony and aluminium respectively to the layer. A layer 9 of the high resistivity desirable in a unipolar transistor may be provided in the above devices by diffusing impurity into the surface of the body to produce a layer of graded resistivity and subsequently etching or grinding off the lower resistivity outer parts of the layer. Alternatively, the layer is formed by preferential evaporation of impurity from the surface of a doubly-doped body. The further layer may be produced by a subsequent diffusion, where necessary through a mask, or by alloying evaporated impurity deposits into the first layer. In embodiments in which the further and first layers are coextensive at some stage of manufacture they may be produced by simultaneous diffusion of a donor and acceptor into the body. A particularly thin and high resistivity first layer may be produced if both a rapid and a slow diffusing impurity characteristic of the conductivity type of the body are used in this process. Alternatively, the rapid diffusing impurity may be introduced in a subsequent diffusion step.
